The operators of an X-rated online video game on Wednesday debuted Utherverse.com, an adults-only site that aims to duplicate the success of wildly popular teen hangout MySpace.com.

Owners of the new site, who recently launched RedLightCenter.com, expect to have more than 1 million registered users by the end of 2006 and encourage members to upload erotic photos and to complete fantasy profiles.

Brian Shuster, chief executive of Utherverse.com Inc said people under the age of 18 are banned from using the new social networking site — a move that should help the upstart online community avoid MySpace.com’s No. 1 pitfall: pedophiles.

Teenagers, young adults and some full-fledged adults have flocked to News Corp.’s MySpace property to socialize, share interests and find dates.

But the site has also been fertile ground for some sexual predators, who have attracted the attention of parents and U.S. law enforcement following multiple reports of sexual assaults to minors.
